Engage with this announcement at the AR3 investor hub. Australian Rare Earths Limited (ASX: AR3) is pleased to announce a second update of the assay results from its drilling campaign that commenced in October 2023, aimed at expanding and upgrading the Resource at the Company’s Koppamurra rare earths project in South Australia. The drilling program, which began in October 2023 has covered approximately 8,750 meters for 694 holes. It is focused on extending the known mineralisation in an area that has not previously been drill tested and resource definition upgrades in the southern resource area. The latest batch of assay results completes the southern portion of the drilling program, specifically targeting resource definition and upgrades within the border forest area (Figures 1 & 2). The assay results continue to support the high grade and shallow nature of the Koppamurra mineralisation (Figure 3 & 4). Approximately 50% of the 4800 assays sent for analysis from the drilling program have been received so far, with the remaining assays expected to arrive during the first quarter of 2024. These pending assays are from the road verge drilling portion of the program which targeted an untested 10km-long northern strike extension of the Koppamurra Resource (Figure 5). AR3 Chief Executive Travis Beinke said: “We are thrilled with the latest assay results from Koppamurra, which continue to reinforce the significant potential for a shallow, high-grade subset of the broader rare earth deposit. The identification of additional high-grade mineralisation within the previously delineated resource area is particularly encouraging and will continue to inform our province development planning in parallel with our ongoing process flowsheet optimisation. “We look forward to receiving further assay results from drilling of the untested 10km-long northern strike extension of the Koppamurra Resource.” Figure 1 - Border Forest drilling.

Measures taken to maximise sample recovery and ensure representative nature of the samples. Whether a relationship exists between sample recovery and grade and whether sample bias may have occurred due to preferential loss/gain of fine/coarse material. • • • • • • Drilling was completed using a Mcleod or Wallis air ore drill rig (Landcruiser 6x6 or similar) for the drilling. Aircore drilling is a form of reverse circulation drilling where the sample is collected at the face and returned inside the inner tube. The drill cuttings are removed by injection of compressed air into the hole via the annular area between the inner tube and the drill rod. Aircore drill rods used were 3 m long. NQ diameter (76 mm) drill bits and rods were used. All aircore drill holes were vertical with depths varying between 2 m and 36 m. Drill sample recovery for aircore is monitored by recording sample condition descriptions where ‘Poor’ to ‘Very Poor’ were used to identify any samples recovered which were potentially not representative of the interval drilled. A comment was included where water injection was required to recover the sample from a particular interval. The use of water injection can potentially bias a sample and very little water injection was required during this drilling program. No significant loses of samples were observed due to the shallow drilling depths (<36 m). The rotary splitter was set to an approximate 20% split, which produced approximately 1.5 kg sample for each meter interval. The 1.5 kg sample was collected in a prenumbered calico bags and the remaining 80% (5 kg to 8 kg) was collected in plastic UV bags labelled with the hole number and sample interval. At the end of each drill rod, the drill string is cleaned by blowing down with air to remove any clay and silt potentially built up in the sample pipes and cyclone.

Geological logging data for all drill holes was qualitatively logged onto Microsoft Excel spreadsheet using a Panasonic Toughbook with validation rules built into the spreadsheet including specific dropdown menus for each variable. The data was uploaded to the Australian Rare Earths Azure Data Studio database. • Every drill hole was logged in full and logging was undertaken with reference to a drilling template with codes prescribed and guidance to ensure consistent and systematic data collection • 1 m aircore sample interval were homogenised within the cyclone and the rotary splitter was set to an approximate 20% split producing around 1.5 kg sample for each metre interval. • The 1.5 kg sample was collected in a prenumbered calico bag and the 80% (5 kg to 8 kg) portion was collected in plastic UV bags labelled with hole identity and interval. • Duplicates were generally taken within the clay lithologies above the basement as this is the likely zone of REE enrichment. These duplicate samples were normally collected by using a second calico bag and placing it under the rotary splitter collecting a 20% split but due to the difficulties of placing a second calico bag under the rotary splitter during sample collection, some duplicates were collected by hand from the plastic UV bags which captured the other 80% of the material recovered from any particular interval. • The material in the plastic UV bags was mixed up and every attempt to take as representative sample of the material as • sampling. Whether sample sizes are appropriate to the grain size of the material being sampled. Quality of assay data and laboratory tests The nature, quality and appropriateness of the assaying and laboratory procedures used and whether the technique is considered partial or total. For geophysical tools, spectrometers, handheld XRF instruments, etc, the parameters used in determining the analysis including instrument make and model, reading times, calibrations factors applied and their possible by hand was made and then placed in a pre-numbered calico bag. • The 1.5 kg sample collected in the calico bag was logged by the geologist onsite. The logged samples were placed in polyweave bags and sent to Naracoorte base at the end of each day. The polyweave bags were then placed on pallets and dispatched to Bureau Veritas laboratory in Adelaide in Bulka Bags. • The remaining 80% split from the aircore interval was stored for future reference. • Field duplicates of all the samples were completed at a frequency of ~1 in 34 samples. Field standards were inserted into the sample sequence at a frequency of ~1:57. Standard reference Material (SRM) samples were inserted into the sample batches at a frequency rate of 1 per 10 samples by the laboratory and a repeat sample was taken at a rate of 1 per 21 samples. • A rig geologist oversaw the sampling and logging process while a second geologist selected samples for analysis based on the logging descriptions and Pxrf analysis. Clay rich sample and those adjacent to the limestone basement contact were selected for assay. REEs are known to be contained within the clay component of the sediment package based on analysis of XRF data and previous exploration work. • The detailed geological logging of samples provides lithology (clay component) and proximity to the limestone basement which is sufficient for the purpose of determining the mineralised zone. • The 1.5 kg aircore samples were assayed by Bureau Veritas laboratory in Wingfield, Adelaide, South Australia, which is considered the Primary laboratory. • The samples were initially oven dried at 105 degrees Celsius for 24 hours. Samples were secondary crushed to 3 mm fraction and the weight recorded. The sample was then pulverised to 90% passing 75 µm. Excess residue was maintained for storage while derivation, etc. Nature of quality control procedures adopted (e.g., standards, blanks, duplicates, external laboratory checks) and whether acceptable levels of accuracy (i.e., lack of bias) and precision have been established. • • • • • • • Verification The verification of the rest of the sample placed in 8x4 packets and sent to the central weighing laboratory. All weighed samples were then analysed using the Multiple Elements Fusion/Mixed Acid Digest analytical method; ICP Scan (Mixed Acid Digest – Lithium Borate Fusion) Samples are digested using a mixed acid digest and also fused with Lithium Borate to ensure all elements are brought into solution. The digests are then analysed for the following elements (detection Limits shown): Al (100) As (1) Ba (1) Be (0.5) Ca(100) Ce (0.1) Co (1) Cr (10) Dy (0.05) Er (0.05) Eu(0.05) Fe(100) Gd (0.2) Ho (0.02) K (100) La (0.5) Lu (0.02) Mg (100) Mn (2) Na (100) Nd (0.05) Ni (2) Pr (0.2) S (50) Sc (1) Si (100) Sm(0.05) Sr (0.5) Th (0.1) Ti (50) Tm (0.2) U (0.1) V (5) Y (0.1) Yb (0.05) Zr (1) Field duplicates were collected and submitted at a frequency of ~1 per 34 samples. Bureau Veritas completed its own internal QA/QC checks that included a Laboratory repeat every 21st sample and a standard reference sample every 9th sample prior to the results being released. Analysis of QA/QC samples show the laboratory data to be of acceptable accuracy and precision; Australian Rare Earths submitted field standards at a frequency of ~1:57 samples. Australian Rare Earths requested BV insert blank washes at a frequency of 1:40 samples. These blank washes were inserted in the sample sequence behind samples which were thought to be mineralized to ensure that no contamination from higher grade samples was occurring. Frequency of blank samples totaled 1 in 24 samples. The adopted QA/QC protocols are acceptable for this stage of test work. The sample preparation and assay techniques used are industry standard and provide a total analysis. • All results are checked by the company’s of sampling and assaying significant intersections by either independent or alternative company personnel.

Field based geological logging for drill holes was entered directly into an Excel spreadsheet format with validation rules built into the spreadsheet including specific drop-down menus for each variable. This digital data was then uploaded to the Australian Rare Earths Azure Data Studio database. Assay data was received in digital format from the laboratory and was uploaded Australian Rare Earths Azure Data Studio database. Field and laboratory duplicate data pairs of each batch are plotted to identify potential quality control issues. Standard Reference Material sample results are checked from each sample batch to ensure they are within tolerance (<3SD) and that there is no bias. The field and laboratory data was exported and imported into Datamine by IHC Robbins which is appropriate for this stage in the program. Data validation criteria are included to check for overlapping sample intervals, end of hole match between ‘Lithology’, ‘Sample’, ‘Survey’ files and other common errors. Assay data yielding elemental concentrations for rare earths (REE) within the sample are converted to their stoichiometric oxides (REO) in a calculation performed within the database using the conversion factors in the below table. Rare earth oxide is the industry accepted form for reporting rare earths.

Topographic DTM surface over the northern area of the resource (Frances Exploration Target area) is derived from DGPS drill collar positions at this stage of exploration and the RL has been corrected using An Australian wide SRTM. The 1 second SRTM Level 2 Derived Smoothed Digital Elevation Model (DEM-S) is derived from the 2000 SRTM. The DEM-S has a ~30m grid which has been adaptively smoothed to improve the representation of the surface shape and is the preferred method for shape and vertical accuracy from STRM products. The smoothing process estimated typical improvements in the order of 2-3 m. This would make the DEM-S accuracy to be of approximately 5 m. The accuracy of the locations is sufficient for this stage of exploration. The holes were largely drilled at between 100 m and 400 m spacings along accessible road verges. Drill spacing within paddocks and forested areas was largely completed at 100 m to 120 m spacings, with a small portion of holes drilled at 60 m spacings.

Exploration done by other parties Acknowledgment and appraisal of exploration by other parties. Details regarding royalties are discussed in chapter 3.4 of Australian Rare Earths Prospectus dated 7 May 2021. Exploration activities by other exploration companies in the area have not previously targeted or identified REE mineralisation. Historical exploration activities in the vicinity of Koppamurra include investigations for coal, gold and base metals, uranium, and heavy mineral sands. Geology Deposit type, geological setting and style of mineralisation. Historical exploration by other parties is detailed in Chapter 7 of Australian Rare Earths Prospectus dated 7 May 2021. The Koppamurra deposit is interpreted to contain analogies to ion adsorption ionic clay REE deposits. REE mineralisation at Koppamurra is hosted by clayey sediments interpreted to have been deposited onto a limestone base (Gambier Limestone) and accumulated in an interdunal, lagoonal or estuarine environment. A dedicated research program investigating the source of the REE at Koppamurra is ongoing, with no definitive source of the REE confirmed to date although preliminary results of this study have ruled out the alkali volcanics in southeastern Australia which was originally considered. Mineralogical test work conducted on clay sample from the project area established that the dominant clay minerals are smectite and kaolin, and that the few REErich minerals detected during the SEM investigation are not considered inconsistent with the suggestion that a significant proportion of REE are distributed in the material as adsorbed elements on clay and iron oxide surfaces. There are several known types of regolith hosted REE deposits including, ion adsorption clay deposits, alluvial and placer deposits. Whilst Koppamurra shares similarities with both ion adsorption clay deposits and volcanic ash fall placer deposits, there are also several differences, highlighting the need for further work before a genetic model for REE mineralisation at Koppamurra can be confirmed.
